Lopsided 51 is an 18 piece burr with an unusual and unique shape that makes this puzzle more interesting. All axes are offset by one unit giving the burr a 'lopsided' appearance.
Because the pieces are offset this also requires the burr stick lengths to be longer by 1 unit, the sticks are 9 units long.
